IRwin® Methane Leak Detector is an innovative, portable natural gas detector for easy gas pipe survey and gas leak detection. It is developed in accordance with many national directives, such as the DVGW (Deutscher Verband des Gas- und Wasserfaches) directive. The IRwin SX-models are certified for use in Zone 0, classification Ex II 1G, Ex ia IIC T3 Ga. The integrated proprietary infrared sensor system (patents pending) has a fast reaction and short recovery time. The system prevents false leak alarms and ensures correct and fast leak evaluation. The specially developed Gas Chromatograph (GC) and IR-sensor combination allows fast distinction between marsh gas and natural gas from all known natural gas sources. The IRwin GC gives fast test results, even at low ethane concentrations, from 1000 ppm methane leaks. IRwin is able to measure methane according to the traditional operating modes required by DVGW G 465-4, such as "Inspection above-ground" and "Measuring bar holes". The...

ASCO CO2 Gas Detectors are used to protect personnel wherever CO2 gas or dry ice is used in closed areas, for example during dry ice blasting or when producing dry ice. ASCO offers wallmounted solutions for area monitoring and portable devices for personal protection. ASCO CO2 Gas Detectors ensure continuous and automatic CO2 content measuring in the ambient air using infrared absorption measuring (NDIR). This technology is very troubleresistant to temperature variations or air draughts and therefore measures very accurately. The CO2 gas detectors are very simple to handle and all components are built splash proof.

The GasPro gas detector can be equipped with sensors for up to five gases with ATEX approval. With the option of equipping the gas detector individually with various sensors, the GasPro gas detector is ideal for use in sewers, sewage treatment plants, landfills, ships, chemical and oil processing industries. An important unique novelty "positive safety" display. The GasPro signals the status at a glance via a three-color LED, green display = everything OK, yellow display = still OK, but a check is due soon, red display = not OK Particularly noteworthy is the loud alarm at 95 db and the optical signaling indicated by two LEDs that can be recognized from each side. The measured gas concentrations are saved every 10 seconds and stored in the internal memory. In addition, various events (switching on, alarm, calibration) are stored in the memory. The collected data can be transferred to a PC with a USB cable. A charging station with interface or a calibration station are also available.

Specially developed for the diverse tasks on the construction site, the Schütz Messtechnik company offers tailor-made measuring tools that reliably and comprehensively support the craftsman in all of his work “all around gas”. The complete solution for the load, leak tightness and usability test on gas pipes can be carried out safely and quickly, including documentation. GDPR-compliant as all personal data is protected against unauthorized access by a PIN. The measurement result can be printed out at the test point on site (optional), fully automatically and without interrupting the system. The professional solution for all measurements according to TRGI The prescribed load tests, tightness tests and usability tests, in the interior installation are possible with just one measuring device With integrated pump for pressure generation Very short measuring time through reference leak measurement PC software included

With the very simple operation and the generated and saved measurement protocol, the documentation can be created quickly and completely reproduced. It is possible to save the measurement data in the device and to print it out again later. No tracer gas nor a second measuring device are required for use. The internal battery, the 230V charger or the 12V vehicle voltage can be used for the energy supply. All included in a complete set. Ethane is always contained in natural gas; evidence of this gas is also evidence of natural gas. A lengthy gas analysis is normally required to prove beyond any doubt that the measured gas concentration is actually natural gas and not swamp gas. This, also due to the sampling, a difficult and time- consuming process, is completely eliminated. Measurement and sampling directly at the borehole is easily possible. The printout can take place after the measurement.

With the GPL 3000 you can detect the smallest of leaks. Leak detection is particularly problematic for seals with swellable materials. The leak detection sprays cause the sealing materials to swell and the leak is temporarily sealed again. The use of a gas detector is essential in this area. The sensor in the GP 2000 is protected from dirt and mechanical stress by a metal protective cap. Clear display of the measured values makes it easy for inexperienced users to find leaks. Together with the robust metal sensor head and the stable casing, the GP 2000 is a professional leak detector for everyday work.

In order to ensure that castings, valves, pumps, hoses and other components or groups have been manufactured free of leakage, they are tested in non-destructive leakage tests. Oxygen, air, nitrogen or sulfur hexafluoride (SF6) can be used as the test medium.

The INFRA.sens® was specially developed for high-quality NDIR gas analysis. In the design phase, special emphasis was placed on high stability and a low detection limit. With the use of high-performance light emitting diodes (IR-LED) and thermal micro radiators, which were adapted to the needs of gas measurement technology, these goals were achieved in full. In the spectral range from 2 μm to 12 μm, carbon dioxide, carbon monoxide, hydrocarbons and nitrous oxide can be reliably detected up to the ppm range with this new sensor platform.

While introducing a new line of gas analysis equipment to the market, we offer a fundamentally new concept of gas analysis systems based on replaceable modular gas analyzers GAOS SENSON-SM-9001. Advantages: - Radically reduced downtime required for calibration and repair - Reduced spare equipment costs - Increase the offline resource of remote objects - Extra-low delivery times New concept: - simplifies the replacement of gas analyzers for calibration and in the event of a malfunction – in the case of GAOS SENSON it is as simple as changing a light bulb, no need to dismantle/change the entire device. That is, it is enough to change a lightbulb, not a chandelier; - it dramatically reduces the stock of replacement systems in volume and cost – only the GAOS SENSON-SM-9001 modules are needed (supply of light bulbs, not chandeliers); - requirements for the qualification of staff (there is only one requirement – accuracy) are reduced.

The MX 256 is a digital control unit intended for the detection and measurement of gases present in the atmosphere and more generally for the processing of any digital signal from digital sensors (OLCT 10N types), relay module, analog output module, logic input module. Thanks to its new option, an industrial controller module or remote HMI, it is possible to add analog input modules for sensor-transmitter connection (4-20 mA) and / or relay modules, this allows to not only extend the capacities but also to have event recordings (Location, Alarms,.....) and to have access to the data via the embedded web page.

The Merlin CO2-X can be used independently or can work in conjunction with one of our Merlin gas safety systems. In the event where the CO2 levels rise to a dangerous level, the Merlin CO2-X Monitor will sound an audible alarm to alert the user of the danger, automatically drive ventilation fans reducing CO2 & temperature as well as shutting off any connected utilities such as gas solenoid valves. An alarm condition can also be communicated to building management systems.

The Merlin GDPX+ is a 16 zone gas pressure proving & detection panel which can be used in many applications, e.g. mechanical rooms, car parks, shopping centers and the most common being a boiler house application. Utilizing a solenoid valve and a pressure transducer the Merlin GDPX+ will check for a pressure drop or leak in the downstream line before allowing the gas to be supplied. Once gas has been supplied the unit will constantly check the incoming gas supply pressure to ensure that a naked flame cannot be extinguished by a weak draft.
